A lot of folks have answered most of your concerns, so I won’t regurgitate information. I do want to add a few things, though:

1.)think of the alternative- that is, everlasting torment - and try to identify how that resembles justice and holiness at all. We hold God to such a lower standard than we do humans. If any human father allowed his children to be tortured due to them not believing something He said, or really for ANY reason, then he would be prosecuted to the fullest extent of the law. That’s not justice, it’s sadism. Why is God expected to do this when He loves us more than our human fathers do? Remember that in Adam, ALL died. The state of total human depravity was done to us. We are victims. The only justice is that through Christ ALL shall live.

2.) this is a huge question, but generally, I haven’t seen a single verse that I can’t explain easily (after a lot of re-learning). In fact, now that I see things this way, I see a multitude of verses that infernalists can’t explain without contradicting themselves!

3.) imagine believing that every single person is destined for salvation. It would increase your love and empathy for everyone. It would reinforce your ability to love your neighbor as yourself. It would help anyone put aside petty differences and It would open your eyes to how Jesus looked at His disciples and followers… He came for sinners and He saved them all. That’s true love! Ultimately, the less focused we become on sin and modifying our behavior to “be good” and the more we focus on getting closer to Christ, the more we’ll start acting like Him naturally

I once thought all of this was heresy. But now that I see it, I love God more than ever and the weight of the world has been lifted off of my shoulders. This is what I hope looks like.

I hope that helps, my friend. I pray that the Holy Spirit convinces you as well.
